This invention relates to n. hook cover` adopted lto be applied to nbool: in orderto protect the some, and one object of the V.1nvention isto provide n book cover which 5 may he easily up lied and is soconstructed that it muy he et justed to Aaccommodate 1tself to thethickness of the hook.

Another object of the invention is to--so form the cover that theportion which covers l0 the binding of the book will ver)1 eieet-ivelyshieid the outer face thereof and also protect its upper ond lower edgesend ot tho seme time to so cover that openings will he provided through15 which the title and the uut-hor of theiiooltV will be exposed or etleast eportion of the binding disclosed to vienr so that ebook may hereadily identified either by its title or the color of the binding. 2o

vde the portions the hacks of the hook with pockets in which clippingsor papers cont-dining notes relating to the book may be placed wherethey` will be readily accessible when wanted,

Another object of the invention is torovide :mover which will be chen topro uce, strong and durable and muy e easily npplied to o. hook of estende-rd size und ad- ]usted to accommodate itself to the thickness ofthe book.

panving drawing, wherein The invention is illustrated inthe accom-f thecover applied to s, ook;

Fig. 2 is n. transverse sectionalV view through the book and cover takenon the line 2--2 of Fig. 1; l

Fig. 3 is a. fragmentary sectional view taken on the line '3 3 of Fig. 1with the pages of the bool: omitted. for the sake of clem-ness. and iFig. 4 is n. vieu" shonvino the cover rcmovrd from the book endplaced'ilet.

The cover constituting the Suliject-lnntter of this invention has beenshown applied to u book 1 which isof o standard size and provided withthe usual backs 2 applied to the pages of, the hook in the usuel mannerond o connected by the usuel binding 3. The cover -consists of com unionsections 4, each of which is prefere lg formed of stiliY pager, elthoughenv suite le materiel may e eniployed, en blanks from which the coversections nre formed are provided with ivin s 5 which ere foldedinwardly, es shown in ig.

forni this portion of they portions of 'beyond the Another ohject'of theinvention is to pro of the cover which fit upon I s l Figure 1 1s operslectwe view showing vmoistened inner surfaces en not be liable to beeasily torn. and lower portions S and 10 of the tongues 4, endendportions 6 folded inwardly and secured upon we seen that cach coversection is of on envelo ve-like formation and may be very easily slidinto pluce upon the hacks of the hook.

The wings 5 terminate in slight-1y spaced relation to the inner ends ofthe cover seetions and it is contemplated that the depth of the envelopefrom the outer end ofa .cover section to the inner ends of the'sidewings 5 will correspond to the width oi the hoek of n hook to which thecover is to be applied. Therefore, when the covers a-re-nppiied to thebacks ofa book, the inner or roerend 4 book und may oe folded to' overIsp the side portions of the binding, i as shown nt 7 in Figs. l and 2.Tongues 8 and 9 extend from the inner end of one cover section andcompanion tongues 10 und 11 pro- 'ect from the other cover section andere adapted to be overlapped by the tongues 8 and 9. It should be notedthat the tongues 10 ond 11 are of greater width than the tongues 8 ond 9thereby providing side portions 12 and 13 adapted to be folded into einbracing engagement with the tongues 8 Vsind 9, tis-shown in Figs. Send.4. Thetongues are of suitable length to accommodate a very thick hookof e standard size to receive the cover` sections upon its back,butitwill he evident that, if the'cover is to be applied to a.thinboolr, the, tongues may be cut so that they will. be of the ivgoperlong-th to? extend across the binding. e inner surfaces of the tongues10 `end 11 ere gumined, be'readiiy seen that when they ere moistened andthe. tongues 8 und 9 aplied `to their the side portionsl and 13 foldedinto emhrneing'relntion-'to thev tongues 8 und 9, the tongues of thecover sections will extendA the Wings 5. It will, therefore, l

and; it will the two coverl sections will he firmly oonnectl ed undalsotheir up er und lower-edge porP tions will bestrengt ened sothat-they will The upper 8 and l() project, as shownin Fig. 4, andprovide extensions 14 which may be folded over the upper and lower edgesof the binding ns shown 1n Figs. 1 und 3, and protect these e portionsso that they will not be worn. t will thus be seen that when the coversections are connected by their coereting tongues they will be securelyjoin by spaced portions 15 and 16 which ere of e. length correspendingto the width of the binding end spaced from euch other to defineopenings through which the title of the book und. the nume of the authorYwill be disclosed or et least nortion of the binding exposed to view sodint when n number of books are provided with covers a book which it isydesired to rend or referred to muy be easily identified. By thisarrangement it is not necessary to write the title of the-book upon thecover und, therefore, u cover may be transferred from one book toanother of approximately the saine size und thickness Without confusionoccurring due to the cover being marked.

Mnny persons who rend books or use the-1n :is references desire to makenotes relating to the subject-matter of the book or cut clippingsreferi-'ing to the book from newspapers und the like, und in order thstthese notes and clippinrs mcy be readily accessible, I have provic edeuch covcr section with u pocket 17. Each of these pockets is of nuenvelope formation and is formed with pleated walls 18 so that thepockets muy be extended if the notes and cli pings to be placed thereinare numerous or nlky. The envelopes ero slightly smaller in dimensionsthan the cover sections to which they are applied, us shown in Fig. l,so that they will not project beyond the mui-vins of the book and eachis provided with a closure Hep 19 which serves to tempo rarily close theopen end of the pocket sind muy accommodate itself to the thickness ofthe pocket. A. fastener 2O muy be provided -for each closure if sodesired or they may be left free.

When s cover is to ben plied to n book` the cover sections are nppliecto the backs of the book und if the tongues nre too 'long they nre cutto the proper length. The cover sections .are then removedfrom the hookand placed iin-t upon a table or other suitable su pport so that thetongues 10 and 1]. may be inoistened :1nd the tonoues 8 und 9 secured inoverl ying relation to t lem. After the tongues 8 and 9 have beensecured upon the tongues 10 and 11, the side extensions 12 und 13 arefolded inwardly and secured in embracing relation to the tongues S und9. The tongues of the two cover sections will now be iii-nil).r securedtogether and will be reinforced so that they will not be liuble toeasily teur. The bucks o1' the book can now be turned reurwurdlgy' sothat they extend substantially llcn'izouiul to euch other sind the coversections slid into place upon them. After the rover sections nre inplace, the bucks nrc returnml to their normal positions and the portionsoi. the tongues l 8 und l0 which roject from the upper und lower edgesof the binding folded into place, as shown in Figs. l :incl 3. If it isdesired to transfer the cover to another book, it is merely necessary toagain swing the backs of the book so that they extend reorwurdly fromthe binding nnd slip the cover sections vfrom the backs. The cover canthen be essi-ly applied to another book of a iproxinmtely the salue sizesind thickness. have, therefore, provided a. cover which muyuccellimednte itself to the thickness of a book having backs of n.standard size und further pro` vided si` cover having pockets in whichnotes and clippings having reference to the book may be kept ferrea-dyreference.

Hoving thus described the invention, I claim:

1. A book cover comprising cover sections adapted to cover the bac-ks ofa book and heving tongues projecting from their inner sido edges toextend across the bindin of the hook, the tongues of one' cover sectionoverlying thetonoues of the other-cover section and secured ieretoandniarnnel. portions projecting from the upper nndblower tonguesvadapted to be bent over the ends of the binding of the book to protectthe sanne.

2. A book cover comprising cover sections adapted to fit upon the bucksof n book and bovino' tongues projecting from their inner side edo'es toextend across the binding of the book, the tongues of one cover sectionoverlying the tongues of the other und secured thereto port-ions foldedto cured thereto.

3. A book cover comprisinv' sections euch and having marginal embracethe sume and se of en envelope formation undzndnpted to be fitted `uponthe backs of a book, the outer walls of the cover sections beingextended and adapted to be folded into covering relation to sideportions of the bindingioff a, book and provided with tongue extensionsto extend across the binding, the tongues of one cover section beingadopted to be secured in overlapped relation to the ton ues of the othercover section and having sidiJ extensions folded and secured inembracing relation thereto, certain of the tongues being extended undadopted to bc folded over tho ends of the hinxling to protect theedgesthere-nt.
